I usually try to help out people in case of IRROPS. We, frequent flyers, now what to expect, how to ask for it and how to find options for rebooking. But most other people don't and their travel plans can be messed up greatly by lazy/incompetent agents.
If I see someone struggling with it, I usually ask I they need help. I feel my parents would appreciate it if someone offered their help if they were in that situation.
